PATENT FFICtf WILLIAM H. HOODLESS', OF PHILADELPHIA, PENNSYLVANIA PUMP Applicationvvled February 26, 1927. Serial No. 171,344.

The device belongs to the class of portable drainage pumps that are taken from one locality to another for temporary use. Such pumps are placed without being bolted or otherwise secured thereto on improvised rests' or supports, which usually extend outward. over water or mud. The driving mechanism must usually be placed at quite a distance to secure a sufficiently firm support. The present device, in accordance with the accepted practice, is of the screw lift type, andy consequently the rotating pump Vshaft must be driven very rapidly.

VThe pump must often be transported. to loc'alities4 where no electric power is available,

hence a belt and pulley drive is the only meansof driving it and the pull of the long belt often required brings a heavy overturning pull on the pump pulley tending to overturn the pump. This device is intended to meetthese conditions by usingastructure in which the pump pulley isplaced very nearly on la level Iwith the pump rests: that carrythe pump and would form, if the pump were overturned, the fulcruin about which it would turn. The pump discharge is located well below these pump rests, and the .barrelof the pump is rigidly and strongly secured to these upper parts. The lower part only of the pump .barrel (the part below the discharge) isI normally filled rwith water, andthe weight of this water combined with the leverage arising from its 'poe sition, will insure a steady position to the pump structure. My pump structure A accomplishes these purposes. It has an upper portion, which is a housing containingthe .driving gear placedy at a level very little above pump rests that extend,y broadly, on either side ofit, anda barrel with its dis-V chargeoutlet well below Vthe pump rests andv these parts being rigidly secured together'.

'This structure is hereinafter described and claimed.

Fig. 1 is a side elevation of the pump.

Fig. 2 isa section on line 2 2 of Fig. 1.

Fig. 3 shows a plate before being curved yand flanged that forms part or" they discharge. Fig. 4 is a section on line 4-4 of Fig. 1. Fig. 5- is a vertical section on an is a plan view of the pump rest structure and the parts adapted to secure it to the gear housing. F ig. 7 is a vertical section of the body plate of the intake of which F ig. 8 is a plan view. Fig. 9 is a section of the foot bearing for the screw shaft. Fig. 10 an elevation of the lifting screw, and Fig. 11 a vertical section of the discharge.

The driven gears are bevel gears G2 and G6. The spindle of the gear G6, and of the driving pulley 30, is the shaft 15, which has bearings in the housing formed of the parts 31, 47, G7, and 68. This housing is firmly secured to the collar 48, of the part 32, of the larger part of the housing 34 of the gearn ing. rlhe shaft 15, and its housing and the bevel gears G2 and 6G, are all stock articles and purchasable in the formused in the pump. The main part of the gear housing is formed of the part 34, to which is secured the top plate 33, and the bottom plate 255, which have the annular and inwardly projecting walls 69 and G3 to contain roller bearings 64, 70, and 71.

The housings formed of the above named parts isfirmly secured above and adjacent to the pump rest, by mounting it upon and securing it firmly to the bearing 72, which is preferably in the form of a ring fitting snugly around a top plate 28 of a gland attached to the bottom plate 35 of the gear housing.'V rPhe bearing 72 is carried by inwardly sloping struts 29 which are secured at their feet?? to the bearing plate 41 of `the pump rest, and at their heads 74 to the bearing 72. The bearing plate 41 is preferably fianged to give it rigidity without too kcan be anything strong enough to carry the pumps weight, and to which ordinarily the .pump need not be fastened in any way. 1^"

l being tilted by the belt pull on the pulleyv 30. The bearing plate al, in practice,l is strengthened by the coverI plate` 175, which has the flanges 176 covering the edges of theV ,l i

which are almost or necessity light and 1nplate 41. Y

Seats for the roller bearings in which the shaft l5 rotates, are provided at the upper and lower parts of the gear housing in the cups formed the walls G3?, 'and-i691 its` these bearings kare positioned at some dis# tance from each other the a-Xis ofthe shaft is fixed by them. Bearings at both 03": these cups or at one of them also carry the weight of the'shaft 45, 'the gear., and: the screwY/l,

andy of the water lifted byl it. In the construction shown the roller bearing 64, at the top ofthe gear used to align the shaft only as is also. the roller bearing 7G at the'. bottom of theliousin' but the rol-ler bearing 71 at the bottom of the housing isa carrying bearingy supporting the shaft and its attached: elements. This insures its very Jfree rotation even when weightedvdown by the water the screw is lifting. The gear .housing preferably should contain a quan-y tity of oilor grease sutiicie'nt to cover the gear 62, and? tlieroller bearing supporting the shaftt d'5, will; run, submerged'. Agl'and is locatedk at 'he lower side ot 'the gear housing and'v consistingv in practice of the packing container 73, the nut 76, andthe com:- pression element 75. The upper part of the ackinov container 73 ma Jformk ai late S281 that can beV secured to the bottom ofthe gear housingiand' can beV shapedto fit inh side the bearing- 72. n

The pumpbody 4:4, the breadth ot which exceeds considerably the width of the gear housing, is hung directly fromythe'- pump rest. ln practice,j it is secu-red to thebearing platedby a hanger 42, and inpractic'e both hanger and' pumpbod'y are. circular. It can be made of'qjuite thin sheet metal; for there can be rio-twisting or bending strainfof any greatainount on.'1ttlius addingto the portability of" the pump. The' discharge can made very conveniently by shaping the y ends ofthe plate i6 so that they willlit into the discharge mouth piece 5S and itsmiddle portion. form part' ot the pump body and the portions between the middle portion and the, ends, form the sidesoiv 'the discharge. The'plates 49 form the upper and lower portions ot the discharge` mouth the form of whichA the plates before the flanges 59`are bent up'. as illustrated in Fig. 3. This construction gives the outlet port at the pump body walls a width substantially equal: to the width of the pump body and' withra nearly level bottom, andl is simple and cheap, and

insures the complete discharge of the water beore it rises much above the bottom. It will be seen that by this construction a comparatively small volume oi water concentrated at the lower end or' therpump body which, as before stated, is of large diameter,

livznser belowl the lifting screw:r TheV hangers .50 may` be,v bolted on, as shown in Figs.. l and t, or r'orm part o a casting as shown in f'figs, 7 and 8; A coinbined'reinforcement andl union J8 can be secured to the bottom the pumpfbody, 'as shown in` Fig.` if, to which the hanger carrier 57. can bev attached or asoinewhat diilerentlyv shaped reinforcement and union 99, as indicated in Figs. 7 and 8", used'. Y v Y lower bearing tor-the shaft l5 is carried trom a standard 53,'.preterably peaksnapeu and upwardly projecting 4centrally 'ri-oni the bottoni of' the intake, YthusV assistingle directing they-inflow ot thewater to i-r'tlng rEllis standard'hasa pocket that in the orm of intake show-n iinl Figs. l andl a, has a lining 5l of bearing metal. ln tlie form shown in Figs. 7! and 8 ,the standard is an integrar portion 89 oli ay castnigwvltli the hangers, andf'has a pocket preferably with a lining 90, which iscupped out spherlcally at itsrupperfportion: 91T, and contains an adjustable journal box 95with a lining ol bea-ring metal, 94 formingv the bearingl Jfor the shaftl'. The upper-.portion yor the journalbox tits the portion 97. 'Below the sphericalfly cupped out portion the pocket isextended togive play t'or the adjustment of' 'the journal box. The ad'- justment is made permanent byV the set screws 91, 91.

The water lifting screw inpractice consists of the hub 88- to wliioh'ja're'y bolted the blades 54, 54. The hub is suitably secured vrto theshaftv 45; r'he shaft 45 has the union consistingotlv the Yplates 38 and'39 on the sections' are added to the pump body, the shaft 45 also canV be lengthened.V The addr tional sectionsxcan be added" to the pump body either below or above V the discharge. Ifclaiin,` Y j l; A portable drainage pump intended tovbe carried from light supportsv and pro- Vvided-'with pump rests thatV are widely 'eutended" are carried unconnectedly jby saidkk supports',` comprisingu inA 'combination a pump barrel positioned below said rests and carried rigidly therefrom and having an intake and discharge mouth below the same, a water lifting screw in said barrel, gearing positioned above said pump rests, supports for said gearing extending from said rests to said gearing7 a vertical shaft extending fromv said gearing to said water lifting screw7 and aV pulley connected to said gearing; the discharge mouth of said barrel being positioned at such a substantial distance below the pump rests that the moment of the water in the barrel will exceed the moment caused by the operation of the driving ofsaid pulley.
